This objective of this research is to study the development of the pararubber tapping knife in order to determine the optimum of the edge and oblique angle and to compare the efficiency of the electrical motor and Je-Bong knife. The product was manufactured by iron steel carbon S45C and AISI 5160 with 75-90 degree edge knife and 0-45 degrees oblique angle. The results can be concluded that the optimum condition of the edge knife oblique knife and the cutting force were 75 degree 45 degree and 3.51-51.42 N respectively. It was found that the cutting force was straightly increased form 0-51.42 N and then gradually decreased. The energy consumption of timber cutting was 0.00370 J/mm3. The quality of the rubber tap using electrical motor was 72.07% which was higher than 2.8 of Je-Bong knife. As the results this product shows the average of rubber timber which is 2.22 mm. in 22.51 s.

The objective of the study were to produce 5 prototype products made of native fabric Paihoochang Banglen district Nakhon Pathom Province which were facial tissue boxes hanging hand towels bolster cushions bags and tablecloths and to study the opinion’s customer toward prototype products about styles sizes utilizations and attractiveness on different products.

The motivation for buying products was the utilizations. The result of customer satisfaction affected phototype products from native fabric weaving showed that the average highest satisfaction in styles of product was the hanging hand towels A which was decorated by jacket style. The satisfaction of sizes of product showed the average highest was the hanging hand towels A which was decorated by jacket style and B which were decorated in scarf style. The satisfaction of utilizations of product showed the average highest was the hanging hand towels A which was decorated by jacket style. The satisfaction of attractiveness of product showed the average highest was the facial tissue boxes A which was decorated by jacket style. The 4 issues satisfaction of products found that all prototypes was the average high the hanging hand towels A which was decorated by jacket style was the average highest .
